after entering via ctrl+alt+f2 i clean some unnecessary data and files.

which create some temporary empty space so that i can login as normal user
then i removed all data on trash.

but again in doing sudo apt-get update or upgrade same issue appears.

also on my system i am using windows 7 along with ubuntu 12.04 in my case
when i log in using windows it works perfectly.

i am not sure is it issue regarding disk partition where my ubuntu tooks
some extra space as required

^ one problem at a time, ok?
right now we're talking about graphics.
however, not being able to update/grade is a serious problem.
please start a new thread for that.

============================================

i'm sorry, i missed one sign there (or maybe the forum software swallowed it?).
it should be:
and please use code tags for code, see my signature below.

hello i think the graphics issue was solved but the disk space again show full and it is incresed slowly..


sachin@Atishay:~$ df -h
